The flash and fire (burn) point of Aroelors, Pyranols, Inerteens, and Tri-Tetrachlorobenzene Blend shall be determined in the Cleveland Open Cup Tester, following the procedure (ASTM Designation B9246) described
In 1949 Book of ASTM Standards, part 5* p. 716-718.
For our purposes, however, it is not usually necessary to make the complete test (Complete Procedure) as given below (A). On routine samples of Pyranols 14?6 end 1482 merely use the abbreviated test (Abbreviated Procedure) for Fire (Burn) Point described under (B) at the end of the method-
Fill the cup to about 3/8"- from the top with the sample.
2. Insert a 20 - 760F, range- ASTK Oj>en Flash (1 inch immersion) thermometer so that the bulb is l/4K off the bottom and midway between the center and the back edge.
3. Adjust the flame so that the rise of the sample's temperature will be at the rate of 9 - 11?* per minute.

4 ,, Adjust the testing flame so that it will be produced through a
blow-pipe with an opening l/32'- This flame should be' only a bead 5/32tt in diameter.

5. When visible vapors start to rise from the product under the heat, carry across the surface of material the small bead flame (Step 4 ) * The test f lease should never be allowed to get any lower than a height of the too rim oi the cup.
6Carry the flame directly across the product, as in Step 5. every
five degrees Fahrenheit until the rising vapors flash beck to
the material under the test.
.
7. Record the temperature at this time as the Flash Point.
8. Continue to pass the flame bead across the sample (Step 5) every
five degrees Fahrenheit until the vapors flash down to the material
and continue to -burn for at least 5 seconds, .

9. Record this temperature as the Fire (Burn) Point.
MSI1 Always read the temperature before testing as the flash tends to increase the temperature "
10. Convert the reading to centrigrade units,.

1. Fill the cup with the - sample to within 3/311 of the top and heat to boiling under a well ventilated hood.
2. As the material cones to a boil pass a test flame (see Step 4,
- Complete Procedure) across the top of the cup [Sisp 5, Complete
Procedure).
3. Note if the sample burns for five seconds or mors.
4. If the material does not burn for 5 seconds? report the Fire (Burn) Point as > B.P. (above boiling point j.
3, If a positive result (the sample barns for 5 seconds or more)
